“…Due to the high protein content of DPC, it can be used as an excellent and natural substrate to produce glutamic acid through a submerged fermentation process using Corynebacterium glutamicum (Davati et al, 2010). In addition, the inclusion of DPC in ruminant diets improved nutrient digestibility, milk yield, and milk composition; the study revealed that there were no negative impacts on treated animals' health (Morsy et al, 2021). The extraction of proteins from DPC may open new horizons for the utilization of such proteins in food and non-food applications.…”

Date palm is the most important fruit crop in the Middle East, North Africa, and Southwest Asia. However, a large amount of waste is generated through various industries related to date processing. Date press cake (DPC) is the main by-product of the date honey or syrup industry, where it gives 17–28 g of DPC /100 g of fruit and is usually discarded as waste. Due to its higher content of nutrients and bioactive compounds, it can be valorized through inclusion in various food and nonfood applications. The potential applications of DPC as a promising ingredient and innovative substrate in different applications were discussed in this review, including chemical composition, nutritional value, functionality, current applications of DPC, limitations, and future trends.

“…Therefore, exploring alternative feeds (e.g., agricultural byproducts) and improving the nutritive value of available ones are recommended. Mechanical, chemical, and biological treatments of low-quality feeds can be used for this purpose [ 1 , 2 ]. Date palm ( Phoenix dactilifera ) leaves (DPL) byproduct is one of the major crop residues in Egypt and many other arid regions.…”

The aim of the current study was to evaluate the ensiling of date palm leaves (DPL) with organic acids (lactic or malic acid) for 45 day as a feed for lactating ewes under desert conditions. Two weeks before expected parturition, 50 multiparous lactating Farafra ewes (mean ± SD: 2 ± 0.3 parity, 34 ± 1.9 kg bodyweight, 25 ± 2.4 months of age, and 555 ± 13.0 g/day of previous milk production) were equally divided into five treatments in a completely randomized design for 90 day. The ewes in the control treatment were offered a diet composed of a concentrate feed mixture and DPL at 60:40 on a dry matter (DM) basis ensiled without additive. In the other treatments, DPL (ensiled without organic acids) in the control treatment was replaced with DPL ensiled with lactic or malic acid (at 5 g/kg DM) at 50 or 100% levels. Organic acids linearly and quadratically increased (p < 0.01) DPL and total intakes and digestibilities of DM, organic matter, crude protein, and nonstructural carbohydrates without affecting fiber digestibility. Malic and lactic acid treatment also increased the concentrations of ruminal total volatile fatty acids, acetate, propionate, and ammonia-N. Additionally, malic and lactic acid-treated DPL increased serum glucose concentration and total antioxidant capacity. Without affecting daily actual milk production, treatments increased (p < 0.001) the daily production of energy-corrected milk (ECM), fat-corrected milk (FCM), milk energy output, milk contents of fats, and feed efficiency. Organic acid-treated DPL increased (p < 0.05) the proportions of total polyunsaturated fatty acids and total conjugated linoleic acids and the unsaturated to saturated fatty acid ratio in milk. It is concluded that feeding DPL ensiled with malic or lactic acid at 20 or 40% of total diet DM increased daily ECM and FCM production, nutrient utilization efficiency, and milk quality. No differences were observed between lactic and malic acid treatment of DPL during ensiling; therefore, both of them are recommended to treat DPL for silage preparation.

Immunometabolic response in Egyptian water buffalo cows during the transition period

2021

Background and Aim: The transition period is extremely critical for pregnant producing animals. However, there is very limited research on the metabolic and immunological changes in Egyptian water buffalo cows during the transition period. Therefore, this study was conducted to investigate the immunometabolic changes occurring during the transition period in Egyptian water buffalo cows. Materials and Methods: A total of 50 multiparous pregnant Egyptian water buffalo cows were subjected to weekly blood sampling 3 weeks before calving and 3 weeks after calving and on the day of parturition to determine the complete blood count, including red blood cell count, total leukocyte count (TLC), differential leukocyte count, hemoglobin level, and packed cell volume (PCV). Some selected serum biochemical and immunological parameters were analyzed, including serum glucose, beta-hydroxybutyric acid (BHBA), non-esterified fatty acids, triglycerides, high-density lipoprotein, low-density lipoprotein (LDL), very LDL (VLDL), cholesterol, total protein, albumin, globulin, creatinine, blood urea nitrogen (BUN), aspartate aminotransferase, alkaline phosphatase, alanine transaminase, gamma-glutamyl transferase, Haptoglobin, and C-reactive protein and the pro-inflammatory cytokines interleukin β1, interleukin 6 (IL-6), and tumor necrosis factor-alpha. All data were statistically analyzed using the IBM Statistical Package for the Social Sciences statistics software. Results: The neutrophil count showed a statistically significant increase at 2 weeks preparturition. There was also a significant increase in PCV, TLC, neutrophil count, and IL-6 and TNF-α level at the time of parturition and even at 2 weeks post parturition, except PCV that returned to normal levels in the 1st week post parturition. BHBA and BUN levels were increased significantly in the 2nd and 3rd weeks postcalving. Serum creatinine and VLDL levels were decreased significantly at the time of parturition, and VLDL levels showed a significant decrease even till the 3rd week postcalving, whereas creatinine levels gradually returned to the pre-calving levels in the 3rd week postcalving. Other parameters showed no significant changes. Conclusion: The most important immunometabolic changes occur in the first 2 weeks post parturition in Egyptian water buffalo cows, which exhibit a potent, remarkable physiological adaptation achieved by their functional liver, which can help the animal overcome the stressful conditions during the transition period.
